Designing ultra-thin printed dipole arrays based on EBG reflection phase profile

Summary form only given. A study on the effects of the reflection phase profiles of EBG structure on the driving-point impedance of dipole antermas is presented. It is demonstrated that a specific range of phase angles is required to achieve good antenna performance. An actual EBG structure and a printed dipole antenna (0.03λ height) are designed, fabricated and tested. The computed and measured results show that efficient printed dipoles on ultra-thin grounded dielectric substrates can be developed that will substantially reduce the sizes and weight of antenna arrays.
